Mike,
have a look at GNAT: http://www.freebsd.org/cgi/query-pr.cgi?pr=51982
You need to patch your kernel sources a bit (all info in the PR) and
your silo overflows will be gone. I've done that to get a Merlin
U630 working (w/o patching sio.c the card was almost unusable).
Hi,
Thanks for the note. Actually, I have done this in the past
(I am even in the above PR :)), but I had found using the UART driver
instead of sio was better for working around such issues on the
whole. The overflow rate is so high in the case, even increasing the
ticks by 10 doesnt seem to fix the issue. It seems to reduce the
overflows a bit, but nowhere nearly enough
sio2: 108 more interrupt-level buffer overflows (total 108)
sio2: 81 more interrupt-level buffer overflows (total 189)
sio2: 108 more interrupt-level buffer overflows (total 297)
sio2: 81 more interrupt-level buffer overflows (total 378)
sio2: 33 more interrupt-level buffer overflows (total 411)
sio2: 76 more interrupt-level buffer overflows (total 487)
With the uart driver, I am able to talk to the modem OK, but the cpu
is really high dealing with all those interrupts.
I was hoping I could just tell the card to use a different interrupt
like 5 which is available, but I dont know how to do that, or if its
even possible.
